Jack Dorsey launches sun exposure app

Twitter CEO, Jack Dorsey has launched Sun Day, an app that tracks sun exposure and vitamin D intake.

This follows the launch of Bitchat, an app that functions without internet connectivity.

Sun Day helps users monitor UV exposure and estimate vitamin D levels based on location, skin type, and clothing.

The app uses your phone’s location to retrieve the local UV index, allowing manual tracking of sunlight exposure and calculating daily vitamin D intake.

Additionally, Sun Day provides valuable information, including sunrise and sunset times, cloud cover, and personalized burn limits based on the UV index.
